I have déjà vu. I think some OpenArena related site had that design a long time ago, it seems familiar. I like red too, maybe because it's refreshing after the blue or maybe because it get's closer to the Q3 theme. Did you decide for a font for the logo? A different font could spice up the header more.
yeah your right it does look familar but sometimes change is needed it looks nice maybe chaing the color scheme and putting Mega clan all over it??
just kidding xD
